Negative-pressure pulmonary edema and alveolar hemorrhage are potentially life-threatening complications of upper airway obstruction

Negative pressure pulmonary edema and alveolar hemorrhage are potentially life-threatening complications after relief of upper airway obstruction. The laryngeal-pharyngeal obstruction results in high negative intrapleural pressures. The increased intrapleural pressures affect the integrity of the al...

Summary:Negative pressure pulmonary edema and alveolar hemorrhage are potentially life-threatening complications after relief of upper airway obstruction. The laryngeal-pharyngeal obstruction results in high negative intrapleural pressures. The increased intrapleural pressures affect the integrity of the alveolo-capillary membrane due to various factors. This review describes clinical symptoms, etiologic factors, pathophysiology and treatment strategies associated with each of these factors. The aim of this review is to equip clinicians with the knowledge base necessary to identify patients at increased risk for negative pressure pulmonary edema and alveolar hemorrhage.
